EFFECTIVE POPULATION SIZE FOR DIFFERENT TECHNOLOGIES OF POULTRY GENE POOL MAINTENANCE

Despite military operations, the poultry industry has a huge impact on Ukraine’s food security. This is achieved through the production of sufficient quantities of various types of poultry meat and table eggs, which are the most affordable components of the daily food basket of Ukrainians. In order to provide producers (micro, small, and medium-sized farms) with genetic resources for poultry, it is necessary to involve domestically bred breeds through a state program, strengthen integration with large industrial complexes, and attract investment. The research was conducted at the experimental base of the State Research Station for Poultry Farming of the Institute of Animal Husbandry of the National Academy of Agrarian Sciences of Ukraine using genetic resources of chickens of various productivity types from the collection of the national gene pool of Ukrainian poultry breeds. Current paper represents results of scientific research focused on comprehensive analysis of the economic efficiency of maintaining the gene pool of chickens of different productivity types. Based on the results of a comparative analysis, taking into account the effective population size (N≥200 heads), the number of poultry groups using different technological equipment (number of group cages from 14 to 20) is justified. Indicators were calculated for the use of standard premises (12×72; 12×84; 12×96 and 18×72; 18×84; 18×96 m) and the minimum number of gene pool groups of chickens of different productivity directions using domestically produced cage equipment (OKPB-2 type) was established, ranging from 24 (laying hens) to 17 (broilers) to 49 to 34 groups, respectively. The number of cages in the corresponding poultry houses that need to be used to complete the gene pool groups of poultry is, respectively, from 216-324 to 296-444 (for OKPB-2 type equipment) and 272-408 and 376-564 (TBR-2 type). Obtained data can be used in the future for calculations and determining directions for improving the economic efficiency of maintaining the gene pool of chicken breeds of different productivity directions.
